Specification of Letters Patent. Patented S t 3o 1913 hpplication filed April 18, 1912. Serial No. 691,666.

"Be it known that, I, STANLErS. Covnn'r, a citizen of the United States, and resident of ,Montclair, in the county of Essex and State of New J ersey, have invented certainnew and useful Improvements in Chimney-Flue Reversers, of which the following is a speci-' fication. a y

'In "constructing chimneys .it isfrequently found desirable to oifset orreverse the position of one portion of'a fl ie with respect to another portion, and in .chimneys having linings, such as terra cottaand-the like, of oblong rectangularcro ss section, the arrangement of the flues is frequently such that the lining; for one ort-ion of a flue will be turned at right ang to the lining for an upper or lower portionof such flue.

a chimney flue reverser of such construction as to be 'eadily'adapted to aid in reversing the relat ve arrangement of 'one portion 'of a chimney flue with respect to another portion thereof, and to properly fit between the ends of flue linings which are at right angles toe a'ch' other with respect to their greater length. 1 To this end my improved reverser comprisesj a'hollow body or casing having'upper and lower oblon openings, the planes of the 'greater lengt which "openings are disposed at angles with respect to each other',whereby by fitting'my'improved 'reverserwithina flue the position of the flue o'r'a portion thereofabove the reverser may be reversed with" respect to the position of the 'flue'or. a portion thereof below the reverser, the flue linings, whentused, being correspondingly reversed, my reverser' serving in'the naturef'of a liner for thatportion' of the flue in which, the :reverser is. located.

My invention also comprises novel detall's of. improvement that will be more fully hereinafter set' forth and then pointed out Reference is to r ing" drawings 7 forming part hereof, where- 1I1---L Figure 1 is ingat the under side of{ g. 1; Fig. 3 is a a, pers ectivje view similar to' Fig. '3 invert:

perspectiveview of thereverser;- Fig. .4 is

ney flue; and Fig. 6 is a perspective view of a modified form ofr'everser. S 1milar numerals and letters of reference indicate corresponding parts in't-he'several views.

My improved chimney flue reverser, indicatedgenerally at 1, comprises 'a hollow body or casing of suitable material, such as concrete, terra cotta or the like, having at oppositeends o enings 1, that are shown as o long' rectang es or geometrically oblong, disposed with "the-greater length of one opening at rightangles to the greater length of the other opening. As shown, the longer edges 1" of two opposed sides or walls are opposed to the shorter edges 1 of said sides or walls, and the shorter edges 1 of two otherppposed sides or walls"(that are be The object of my invention is to provide tween the edges 1") are opposed to the longer edges 1 of the last named sides or walls (that a'rebetw'een the shorter edges 1'). As shown inFigs. 1 to 5 the sides a, b,

are at right angles to each other, the edge a being inclined between'the' edges 1", 1 of side 6; the'edge d of side a inclines from the edge'l to the edge 1 of said side; the edge 1 of the side f inclines from the edge 1' to the edge 1 of such side, and the side g inclines corresponding to the edges 03, e, whereby marginal-portions of the openings 1", 1, havea common right angle along the edge I), but as the planes of the greater lengths of said openings are shown at right angles to each other, each of said openings extends in its greatest length" beyond the plane of the'c'orresponding side or edge of the width of the opposite opening, whereby a portion ofone opening 1 is oifset with respect to a portion of the other opening 1. The sides a and b are thus substantially.

similar in shape and dimensions,but inverted with respect to each other, and the sldes f and g are also substantlally similar to each other but inverted with respect to oneanother, whereby the effect stated of one opening 1 extending in its. greatest length beyond the plane of the corresponding side of the width of the other opening 1 is In Fig.- 6 the arrangement of the reverser is in general substantially similar to that before described in that the openings. 1 are at right"- angles to each other, but the upper opening 1 overlies the lower opening 1 symmetrically, that is to say, the extension in the form of trapezoids, whereby such trapezoidal sides or walls are of the same angles, and dimensions, but one such side or wall is reversed in position with respect to two adjacent sides or walls.

The reverser is placed at a suitable position within, and at a desired relation to, the

flue 2 of a chimney, and the flue is conto the openings 1 of t structed, below and above the reverser, for a desired distance, with its transverse dimensions or sections corresponding in position e reverser; that is to say, the portion of the flue below the reverser will have its transverse length or greater dimension parallel with the plane of the lower opening 1 of the reverser, and its transverse length or greater dimension above the reverser parallel with the plane of the upper opening 1 of the reverser, and thus at right angles to the greater width of the port-ion of the flue below the reverser.

My improved reverser is particularly useful in connection with linings 3, 4, for the flue, which may be of terra cotta, concrete or other material customarily used for such linings, which linings will be of cross sectional shape and dimensions substantially T the same as the corresponding dimensions of the ends of the reverser. In Fig, 5 the lower portion of the flue and the. liner 3 are represented with the greater width of the flueand the greaterlength of lower opening 1 running rearwardly, and the upper portion of the flue and liner 4 with the greater width running transversely of the sheet, and it will be noted that in this casethe flue ort-ion and lining 4 are offset to one side of t e vertical plane of wall 3 of lining 3. This arrangement of the reverserenables one ortion of the flue and its lining to be 0 set with respectto another ortion of the flue as well as to have the position of one portion of the greater width of the flue reversed with respect to another portion of the flue.

The lining 3 may be set in the chimney as the latter is being built, the reverser 1 set upon lining 3 and the chimney continued, up-

wardly along the reverser, and the lining 4- may be set upon the reverserand the chunney-continued along lining 4.

distance, and then an upper portion of. the I flue is to be built with its greater width at right angles to the greater width of such lower portion of the flue. My improved reverser enables ready building of the flue in such relations,-and is particularly useful, where linin for the flue are used, in aiding the setting of the upper lining that is reversed with res ect to the lower lining,

' the reverser forming a continuation or lini'ng sectionbetween the reversed lining portions.

While the openings 1 of my improved reverser are shown in oblong rectangular form to accord with corresponding oblong. rectangular'linings, it will be understood that the openings 1 of the rev'erser,while made oblong and. substantially at right" angles to one another in the direction of the planes of their greater lengths, may have other cross sections, such as oblong-elliptica An advantage of my invention is that the dimensions of the reverser may besuch that the cross sectional area of the interior or flue portion of. the reverser may be the same at all points of the reverser, thus en- 7 abling a flue, containing the reverser, to be constructed of equal ca acity at all points."

Changes'may be ma e in the details of construction and arrangements set; forth,

within the scope of the appended claims, without departing from the spirit of my invention.
